Cemented carbide button for coal mining have superior wear resistance and impact toughness, and have higher drilling speed than similar products. Long service life, its non-abrasive life is about 5-6 times of the same diameter blade head brazing head grinding life, which is conducive to saving auxiliary working hours, reducing workers' physical labor and speeding up the project. Cemented carbide teeth are divided into coal miner cut-off teeth and roadheader cut-off teeth, of which roadheader cut-off teeth have higher requirements in hardness.

Application

Cemented carbide cut-off teeth are mainly used in mining, tunnel construction and other areas.
